Jame; 1? Jonas ATTORNEYS United States Patent 3,030,671 AWNING TYPE WINDOWS AND LOCKING BEANS THEREFOR James Francis Jones, 9767 NE. 12th Ave., Miami Shores, Fla. Filed Mar. 22, 1960, Ser. No. 16,706 3 Claims. (Cl. 2o 42 The present invention relates to improvements in windows and more in particular to awning type windows having locking means thereon.

Heretofore awning type windows have not had any means for locking them in a closed position, or if locking means have been provided the pins received in the locking means have not protruded through said means, but have been received in channels or grooves in the side of the lock, which have not functioned satisfactorily because any variation in the louvers have allowed the pin to be released from the groove.

It is an object of the present invention to provide locking means for louver and awning type windows each locking means receiving one single pin in an opening cut into the locking means so as to receive the pin at some point remote from the end thereof.

It is a further object of this invention to provide an awning type window in which the various louvers are simultaneously actuated by a manually operated device that will automatically lock each louver in a closed position when the louver has reached that position.

The various features of novelty which characterize this invention are pointed out with particularity in the claims annexed to and forming part of this specification. For a better understanding of the invention, however, its advantages and specific objects obtained with its use, reference should be had to the accompanying drawings and descriptive matter in which have been illustrated and described a preferred embodiment of the invention.

FIGURE 1 is a fragmentary front elevational view, partly in section, of an awning type window construction of the present invention.

FIG. 2 is a fragmentary vertical sectional view substantially on line 22 of FIG. 1 with vents of the awning type window in closed position.

FIG. 3 is an enlarged fragmentary horizontal sectional view on line 3--3 of FIG. 1.

FIG. 4 is a fragmentary vertical sectional view similar to FIG. 2 with the frame structure shown in phanton lines for clarity and the vents shown in open position.

FIG. 5 is an enlarged perspective view of a pivotal locking cam of the present invention.

FIG. 6 is an enlarged perspective view of a pivotal lock of the present invention.

FIG. 7 is a fragmentary vertical sectional view similar to FIG. 2 of a modification showing a one vent window type construction.

Referring more in particular to the drawings, a jamb forming member 20, shown in FIG. 1, preferably made of aluminum, conceals within the lower part thereof a crank shaft 21 which is rigidly connected to the crank link 22 which is operated by the drive link 23 connected to the center of the crank link 22 and to the driven arm 24 which is operated by the gear device 25, shown in FIG. 4. This gear device is operated by the manually rotatable crank 26 shown in the closed position in FIG. 2 and shown in the open position in FIG. 4. The crank link 22 has pivoted to the outer end thereof a connecting link 27. This connecting link is rotatably attached to the slide bar 28 which is held by the slide bar bearings 29 near the bottom thereof and 30 near the top thereof. These bearings are preferably of the nylon roller type, and allow the bar to move upon the actuation of the man- 3,030,671 Patented Apr. 24, 1962 "ice ually operated crank 26. Attached to this slide bar 28 are the vent hinges 31, 31, connected to the top of each vent 32, 32. A link 33, 33 is pivotally connected to the vent at a point remote from the upper end thereof and to the jamb 20. A lower cam 34 is pivotally mounted on the jamb member 20, and has connected to the side thereof the locking bar 35. For each vent there is a locking latch 36, 36, also pivotally mounted on the jamb 20 and pivotally mounted on the locking bar 35. The cam member 34 is shown in detail in FIG. 5 and comprises a boss 37 having a bore therein to receive a screw held pivot member connecting it to the jamb 20. The locking latches 36 are shown in detail in FIG. 6 and have two openings therein, the first opening 39 receiving the pivot member 38 which is a threaded bushing at each vent. A second opening 40 is held by means'of a rivet 41 in pivotal relation to the locking bar 35. Each of these latches 36 as Well as the cam member 34 is preferably made of nylon or some other type of non-corrosive plastic material and each has a slot cut therein to receive a pin. This allows the pin to project through and beyond both the cam member and the latch members so that when the window width is short the pin will project through the holding member, that is, the cam or latch member, a little further, and will not bind as it would if the receiving slot were only a grooved recess in the side of the holding member. If the window width is long the pin will still have engagement with the slot which would not be true if the receiving opening were a recess in the side of the latch or the cam member.

There is a pin 42 projecting from the pivot point of the crank link 22. There are lower pins 43, 43 on each of the vents 32, 32.

While the operating mechanism is described and illustrated on one side of the window frame only, there is a similar mechanism operating on the other side and the two are connected with the crank shaft 21 and operate simultaneously.

The modification shown in FIG. 7, shows a picture window type installation where there is only one vent and this operates on the same principle as the modification shown in FIGURES 1 to 6 inclusive. The vent 46 is held in position by means of the vent hinge 47 which is attached to a slide bar 46 and is held in a closed position by the locking latch 49 which receives and retains a pin 50 on the side of the vent. The locking latch 49 is operated by the locking bar 51 which in turn is controlled by the cam 52 which receives and retains the pin 53 which is attached to crank link 54 which is operated by the same type of mechanism as shown in FIGS. 1 to 4 inclusive.

When the vents are in closed position, as shown in FIGS. 1 and 2, and the manually rotatable crank is operated, the gear device 25 rotates about its pivot point 25' and the arm 24 moves toward the outside of the window. This forces the drive link 23 downwardly and moves the crank link 22 outwardly and rotates the shaft 21 operating the mechanism on the other side of the window. When the crank link 22 moves downwardly the pin 42 which is retained within the lower cam 34 moves that cam outwardly raising the locking bar 35 and releasing the locking latches 36, 36 from the pins 43, 43 on each side of each vent. This allows the vent to move outwardly as the slide bar moves downwardly within its bearing due to the downward force applied by the connecting link 27 to the slide bar. This moves the top of each vent downwardly, the pin 43 having been released, and the vent pivoting on the link 33 moves outwardly.

When the process is reversed and the vents closed due to the bar moving upwardly the pin 42 is received within the cam 34 which moves the locking bar downwardly and pulls the locking latches '36, 36 downwardly over each of the pins 43, 43 on each side (if each vent.

While in accordance with the statutes there has been illustrated and described the best form of the embodiment of the invention now known, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirit of this invention asset forth in the appended claims, and that in some cases certain features of this invention may be used or changed without a corresponding use of other features.
